APPARATUS AND METHOD FOR REMOVING PARTICLES FROM AIR

摘要

An electrically enhanced filter apparatus for removing particles from air passing through the filter in a flow path from an upstream locus to a downstream locus includes: a plurality of electrically conductive particle-permeable electrodes situated in the flow path. A first electrode is an electrically conductive permeable electrode situated substantially at the upstream locus. A second electrode is an electrically conductive permeable electrode situated downstream of the first electrode in spaced relation with the first electrode. The second electrode is coupled with a voltage source sufficient to effect ionizing of the particles passing though the second electrode. A third electrode is situated downstream of the second electrode in spaced relation with the second electrode. A fourth electrode is situated downstream of the third electrode in spaced relation with the third electrode. A particle-permeable filter element is situated between the third electrode and the fourth electrode.
